I know this is a shot in the dark, and I think I might have asked this before but don't remember (for sure) what the answer was. Picked this card up several months ago. As we all know there are a ton of W575-1 type cards with different stamps and printing on the backs. Personally, I categorize them the way Burdick did with the general classification of W575. From a bit of searching it looks like Service Candy Company was started in 1934 though I am not sure where? They moved to Montana in 1957. Has anyone seen any other cards like this with a similar stamp? It looks like the phone number on the back is ALA. 2785-W ......
